FYI, here is a site with lots of programming info.
It is probably where I got the "press on programmer" idea from.
ELM - AVR programmer



Note: I just use a usbtinyisp these days.

FYI, I dug out my parallel port isp programmer just now to see how it does under ubuntu. It hasn't failed once after dozens of attempts. It never worked this good on windows. I'm using 5v power from the usb port to power the target board also.

I just put these commands in a shell script and ran it with sudo (might need tweaking of course), and arduino should have made a hex file already:

Code:
export avrdir=/home/dave/progs/arduino-0011/hardware/tools
$avrdir/avrdude -C$avrdir/avrdude.conf -v -v -v -v -pm168 -cdapa -F -e -Ulock:w:0x3F:m -Uefuse:w:0x07:m -Uhfuse:w:0xdd:m -Ulfuse:w:0xef:m
$avrdir/avrdude -C$avrdir/avrdude.conf -v -v -v -v -pm168 -cdapa -F -Uflash:w:mpguino.hex:i -Ulock:w:0x2b:m

Thanks a bunch DC!. The diagrams were very helpful in getting this thing going again. I had a hard time keeping the wires pressed to the chip when trying to re-burn the chip, the extra socket is a must!

It now runs 100% and I hope to ad the data for the 98 ranger to the wiki page in the next week or so!

ISP programming question

Very interesting info, lot of it.

However, difficult to follow for me. I am a retired forester, just hobbist experimenter with electronics.

Suppose I have a chip (MPGuino chip) already programmed. I need to change units (from english to metric) and some sensor processing calculations.

The only language I know is Arduino 011 (kind of C++) . If I use the USB tiny ISP , can I edit the programm of the MPGuino chip and change some lines with the Arduino compiler from the notebook?

If not possible, what is the easiest way to proceed? Supose I want to use the USBtinyISP device... Can I bought it from you? Can you program my chip?
What solution do you advice me?

Thank you in advance for your help.

just another option for isp programming, I've used this from arduino and it works well with avrstudio as well as other programmers, and the kit is $11 shipped!! I got it with the AVRISP-mkII firmware.
